GAS BURNER.

Application mea July 18, 1924. serial no. 726,738.

To all 207mm it may concern.'

Beit known that I, linnn-ur D. Cnrrns, a citizen of the United ntates, residing at Duluth, in the county ot' St. Louis and State ot' ll/Iinnesota, have invented certain new and useful Improvements in Gas Burners, oit which the following is a spec'tcation, reference being had ther-ein to the accompanying drawing'. u

This invention relates to gas burners and has special reference to a burner used within a furnace such as employed in house heating, or the like.

The principal object ot the invention is to provide a novel form of burner which will produce the greatest amount oi'f heat possible in proportion to the fuel consinned.

Another object is to produce such a burner particularly adapted for convenient installation to an ordinary furnace.

Still another object is to provide novel means Yassociated with the burn-er for retainin g heat and di'ii'using it as nearly as possible within the combustion chamber ot the burner.

@ther objects and advantages of the in vention will appear in the further descrip tion thereof.

Referring now to the accompanying drawing', forming part of this application, and in which like reference characters indicate like parts:

Figure 1 is an elevation, partly in section and partly Vbroken away, of one of my irnproved burners.

Figure 2 is a horizontal section taken on the line 2-2, Figure 1; and

Figure 3 is a section taken on the line 3 3, Figure 1.

The grate of the furnace, the construction of which is not material to the invention, is illustrated at 1, through which is installed the vertically disposed gas supply pipe 2. it being shown as connected below the grate 1 to a horizontal pipe 3 having installed therein the usual gas and air mixing valve 4 which is manually manipulated in the usual manner externally of the furnace walls.

The pipe 2 forms an axial support for the separable burner housing comprising the four parts 5, 6, 7, and 8, the lower body portion 5 of which is mounted upon the circular collar `or ring like plate 9 which rest-s upon the top of the grate. The plate 9 is provided centrally with an upstanding annular ring 10 about weich the lower bod)l portion 5 ot the burner housing rests, and the top wall or plate (i ot' the lower portion ot the housing snugly fitted thereupon by haring a depending flange 1l formed integral therewith which surrouiuls theupper end oi' the lower body portion said plate haring an axial hole lo snugly lit the pipe Q, and also a plurality ot radially disposed ports or openings 12 therein.

The intermediate body portion cylin drical in t'orm and of the same size in diameter as the lower body portion, it having a bottom plate 13 formed integral therewith, having holes 1% 'Formed therein similar to the holes 12, and which register therewith when the intermediate body portion is rotated tor such purpose; there being' a radially :atending handle 15 for such purpose. rl"hese ports are for the purpose ot regulating the supplyY oi" air passing upwardly through the body portion of the burner. The plate 153 of the intermediate portion T is provided with a central axial hole which snugly fits about the pipe 'forming a pivotal mounting for same so that the rotative adjustment ot' the upper portion of the burner may be readily accon'iplished.

Carried upon the intermediate portion 7 is the crown 8 of the burner housing, there being a plurality of narrow spaces or slots 16 intermediate ot the intermediate portion 7 and the crown for the discharge of gas or flame, as the case may be. The upper portion of the crown is ared outwardly so as to extend somewhat beyond the body portion and has formed through the upper circumferential wall thereof a plurality of quite large holes 23 for distribution of the flame or gas, and the entire iiat top of the crown S is provided with any desired number of small holes or discharge orifices 17 for a like purpose.

The nozzle 18 attached to the upper end of the pipe 2 is also provided with a plurality of slots 19 in the upper flaring circumferential portion thereof for the discharge out gas therefrom.

The body portion ot the burner is surrounded within the re boX of the furnace by any desired heat retaining substance such for example as sand and broken bricks or other like material, and the preferred arrangement of this is illustrated as the sand 20 occurring first upon the grate which may be covered with heavy papel', canvas,

or other such material to prevent the sand falling through, and then surmounted with the crushed stone or brick, as illustrated at 21. In this manner means for retaining heat produced by the burner is provided with the least expense possible, and the burner as disclosed has proven very efficient in heat production in that combustion first takes place about the nozzle 18 within the uppermost portion of the burner, and the unburned gases thus produced being confined within the superheated body portion of the burner willl discharge through the crown of the same, and further ignited, intensifying the heat and materially improving the efficiency of the burner.

Vithin the ring 9 and spaced some little.

' distance from the side walls of the body portion of the burner are upright pipes or tubes 22, they being open at both ends forming communication intermediate of the space above the heat holding aggregate and below same so that additional air is allowed to circulate therethrough in providing oxygen for the combustion taking place eX- ternally of the burner, and there may be any number of these pipes as desired, preferably four or more.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. A gas burner of the type described. comprising an upright three-part rotatably adjustable cylinder having an axial burner therein, portions of said cylinder being adjustable about the burner as an axis to regulate the air passing through the cylinder to the burner, the upper portion of said cylinder being outwardly fiared and provided with discharge ports, some of said ports occurring below the flared portion and some above the flared portion.

2. The combination with a furnace hav ing` a fuel grate therein, of a gas burner` within the furnace supported upon the grate comprising arrotatably adjustable upright cylinder, a gas supply pipe disposed axially of the cylinder and terminating within the upper portion thereof, one section adjustably supported upon the other, means for regulating the circulation of air through the cylinder, granular material surrounding the cylinder, resting upon the grate, and graduated upwardly from fine to coarser, and a plurality of upright pipes installed within the granular material and spaced from the gas burner to supply additional air therefor. v

3. A gas burner ofthe type described comprising an upright hollow cylinder, a covering member for said cylinder having ports therethrough, a second cylinder mounted directly upon the cover of the first mentioned cylinder' and having ports therein for optional registration with the ports in said cover, a perforated crown mounted directly upon the second cylinder, and an upright burner within said cylinder forming an axial support therefor, `the terminal of said burnerI occurring within the uppermost cylinder and beneath the crown.

In testimony whereof l hereunto affix my signature.
